For most use cases, e-signatures are considered legally binding if the process meets federal, local and/or international laws and regulations. If you are unsure about your particular scenario, always review your use case with U-M legal counsel (i.e., the Office of General Counsel).
Each user of the system is responsible for ensuring that use of this service complies with laws, regulations, and policies where applicable (reference the Sensitive Data Guide for E-signature). That includes exporting/archiving sensitive documents only to storage services that the Sensitive Data Guide says are appropriate.
Although SignNow offers some cloud storage integrations, they may not be appropriate for your use. For example, documents containing sensitive data should either be transferred from an individual account to a Shared or Team account after they are uploaded to SignNow, or it might be better to store your signed sensitive documents in the University's Document Imaging system, and not in SignNow, for long term storage.
Note: In an effort to protect the university’s sensitive data, the U-M configuration of SignNow has been established such that completed, signed documents are not sent as an email attachment from SignNow. Instead, there is a link provided in the email which takes the recipient(s) directly to the completed document.
